The Barghesi are a hyper-violent extraterrestrial species inhabiting the Grendl Stars, a constellation located within the Eastern Fringe. According to Imperial Records, the Iron Lords, a chapter of Space Marines are or were instrumental in confining the species to the Grendl Stars, and are busy preventing the TyranidHive Fleet Kraken from harvesting their destructive biological potential. Given the power of the Hive Fleets, it can be assumed however that this will eventually prove itself to be a losing battle.
